Often, the most effective approach is to identify and treat the source of the noise based on the results of a noise control survey.Īdministrative controls are policies designed to lower the noise exposure by limiting the time workers spend in high noise areas. However, when eliminating the noise is not feasible, there are approaches to lowering the risk of noise-induced hearing loss, either through engineering a solution or applying an administrative policy to limit noise exposure.Įngineering controls involve modifying the equipment, process, or environment in some way so that less sound energy is created or is transmitted to the workers. Simply put, it is more effective to eliminate or decrease the severity of the hazard than to change the way people work or require workers to wear protective equipment.įor example, an employer can adopt a Buy Quiet approach, specifying less noisy equipment and processes during the design phase. The concept of a Hierarchy of Controls is well established in occupational health and safety.
